The math is right, although I am still trying to find out the predicted or observed mass distribution of galaxies, yes. The infinity is for the edge of a flat disk plane of uniform density, not one with some thickness, but as far as I know, the exact solution for a thick disk is not known either, only approximated, so that is why I am just using the program unless I can manage to work it out through the integrations. But even then, the program does the same thing as the integration, just point by point, and I can vary the mass distribution at will instead of reperforming the integrations accordingly, and it's much quicker to boot.
